IMPROVEMENT IN WHEELS FOR VEHICLES.

Specification forming part of Letters Patent No. 129,518, dated July 16,1872.

Specification describing an Improvement in Carriage-Wheel Hubs, inventedby J ESSE B. BAUMAN, of Shepherdstown, in the county of Cumberland andState of Pennsylvania.

This invention relates to an improvement in carriage-wheels; and has forits object to produce a hub andv peculiar-shaped spokes, which willsimplify the construction of the wheel while sustaining a greater degreeof wear and pressure than, the ordinary wheels heretofore in use. Theinvention consists, chiefly, in the combination of a wooden hub having acentral row of spoke mortises arranged in a zigzag line with two lateralclamping plates or collars, which are provided with internal taperinglugs or projections forming,

' when applied to the hub, mortises or sockets for receiving andclamping the spokes. The second part of my invention consists in themanner of attaching the clamping-plates to the hub by embedding orcountersinking the horizontal flanges formed thereon into the surface ofthe same, and then securing them in place by bands driven over them. Theinvention further consists in connecting the two clamping-collars, afterapplication to the hub, by means of split or bow-shaped keys and wedges,which will allow the spokes to be tightened with facility.

Figure 1 is a longitudinal sectional view of 4the hub. Fig. 2 is a sideelevation of the.

same with parts in sectional detail. Fig. 3 is a section through theline a', Fig. 1.

A represents the body of the hub, formed of wood, and having in itscentral portion, which is somewhat raised, a series of circularmortises, which are arranged in a zigzag line or alternately set to theright or left. B are the spokes, which are formed with round tenons acorresponding in shape to the mortises in the hub, and with squareshoulders b and inclined or tapering surfaces c immediately above thesame. C represents the clamping collars or plates, provided withtapering 'or wedge-shaped proj ections or lugs D on their inner oradjoining faces, which, when applied to the hub, will form sockets forthe reception of the tapering surfaces of the spokes. E are horizontalcircular flan ges, formed or attached to the clampingcollars C, and madein one or more pieces. Said anges E are provided on their under sideswith a rib, F, and pins G, the former of which enters a continuousgroove turned in the hub, and the latter in openings formed in the same.H is the countersunk portion of the hub, formed around the center of thesame, for the purpose of receiving the horizontal flanges E on thecollars C, after which a detachable band or ring, I, is driven over thesame to secure them in place. K are bow-shaped pieces, the ends of whichproject through openings in one of the collars C, while their oppositeends are-secured to the other collar. L are wedge-shaped keys passedthrough the projecting part of the bow pieces, for the purpose ofsecuring the collars, and drawing the same against the spokes wheneverit is necessary to tighten them.

Instead of the fastening device, above described, wood screws, requiringno burr or square head on the outside, may be employed.

I do not confine myself' to the exact construction of the parts abovedescribed, as the hub may be made entirely of metal, with the ilangescountersunk and secured in the manner described; and instead of theclampingcollars being both alike, one of the same may be made plain, andrest directly upon the 'surface of the hub, as shown in the drawing atM.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

l. A carriage wheel hub, consisting of a wooden body, a-st'raightcircumferential row of spokes, and two lateral clamping-collars, whensaid spokes are provided with tenons arranged alternately on theiropposite sides, and the hub formed with a series of zigzag mortises forreceiving the tenons, as herein shown and described.

2. The clamping-collars C, provided with tapering projections D, andhorizontal flanges E embedded or countersunk in the Wooden hub, andsecured in position by bands I fitted over the same, substantially asdescribed.

3. The ribs F and pins G, formed on the horizontal portion of theclamping collars, and entering corresponding grooves and holes in thehub, as and for the purpose specified.

4. The spoke-clamping plates C C, connected together by means ofbow-shaped pieces K and Wedge-keys L, or other equivalent'fast4 eningdevices7 substantially as described and shown.
